What is your most interesting bit of trivia?

I thought I would try this one out for giggles. We obviously have a very intelligent group of interesting people here. I am wondering if we have a good supply of interesting, surprising, or amazing trivia.

Here are a few that surprised the heck out of me.

I am told that the most successful book series in publishing history is Star Trek. I didn't even know about more than 5 or 6 of these. I think there are 50 or 60...maybe even more? I am also told that for a while at least, Klingon was the fasted growing language in the world.

Also, did you know that at least one kind of mouse never pees?

Finally, did you know that jackrabbits should not be able to survive in the desert heat? They cool their blood by pointing their oversized ears at the sky. Since space has a lower black body temperature than the surrounding environment, the wabbit wivves.

In the US, I believe the number of Star Trek books sold a minute is a little over 10 or so, that stat alone gives you a good idea of how successful it is.

Star Trek sucks

The Sand Mouse is it?

EDIT: The Klingon Dictionary is considered to be the fastest growing language [in the galaxy *rolls eyes*]. Not that many people actually speak it fluently, but since it started with no people knowing it, they can call it the fastest growing language. Although I would doubt it because Spanish, French, German, etc. are taught across the country in schools to thousands and thousands of students, and only a couple hundred [max] know Klingon good enough to say they speak it.

I think it mainly has to do with what hand you are. If you are right handed you will notice that your right hand thumb is the one that is doing most the actualy movement, your left thumb will basically go in a less coordinated motion. True though, it is harder to reverse it.

Here's one from Richard Feynman:
Can you pee while standing on your head?
Anyone care to try? Richard did.

OK. How many people can curl their tongue from side to side?
This is a genetic trait and only some people can do it.

My wife saw a patient once who has a condition known as Asides Inversus Totalis. All of the organs are reversed; right to left.

I was working with an MRI crew - I was not there at the time - that scanned a WWI vet. He had a very low quality stainless steel pin in his leg from the war. The MRI removed it for him. Came right out.
